Insulated 250 mm socket extension

The Knipex 98 45 250 is an insulated socket extension designed for electrical work on live equipment. Its 10 inch length and 1/2 inch square drive suit professional electricians and maintenance technicians. The HAWA alloy steel construction provides durability for repeated use. It is rated for both low-voltage and high-voltage applications.

Check drive size and voltage rating

Verify that your existing sockets and ratchets use a 1/2 inch square drive to match this extension. Confirm the insulation rating covers the maximum voltage present in your specific work environment. Ensure the 250 mm length provides sufficient reach without exceeding workspace clearances. The tool is restricted from sale in certain states, so check local regulations before ordering.

Internal and external square drive

The extension features both an internal and external square drive, allowing secure tool retention during adjustment. This design helps prevent accidental disengagement when working on electric motors or panel hardware. The insulation coating directly enables safe operation on energised circuits. No additional accessories or software are bundled with this hand tool.

Questions about this item

Does the Knipex 98 45 250 extension bar include sockets or adapters in the box?

The package contains the 250 mm insulated extension bar with a 1/2" square drive only; sockets and adapters are sold separately.

How do I decide between the 250 mm version and a shorter or longer extension?

The 250 mm length gives 10 inches of reach for deep electric-motor bolts; choose a shorter bar for tight spaces or a longer one when more clearance is needed.

What does the 10 inch length mean when the extension is on a ratchet in a live panel?

The 250 mm shaft keeps your hands further from energised parts while still fitting a 1/2" drive ratchet and socket on electric-motor fasteners.
